2006 clk500. Is there a relay sensor or fuse that I can replace?

The check light has been in for a while now.
It occasionally shut off, especially after it
rains. One day, I was using the auxiliary
power, and there was a click, and no power.
Then there was power, but now it won't start
or even crank/turn over. There's nothing.
Never had an issue with the starter, and the
battery is strong.

As far as your power problem, clean the battery terminals and the cable ends.
If your check engine light is on you need to have the code read to see what is wrong. Don't reset the light until you read the code!
I agree. The light will just re-appear, and in the meantime you could be damaging your catalytic converter, just making things worse -more expensive- depending on what threw the code
Yes, I definitely will. Thank you. As far as the battery goes... I cleaned the nipples and terminals, reconnected, and nothing. Even attempted to have it jumped, and it still didn't crank. Checked my lights, etc, and they are very bright. But I just noticed that along with it, my lights don't work when on auto.
Ok, I re-read your question and it won't start to get to a place to read codes. You can buy/rent/borrow a scanner, they are not difficult to operate. Come back here with code(s) and we are happy to help with a solution
If the battery is good and the connections clean and it still won't start, you may need a new starter.
Ok, the code was P0102. That's the code for the Mass or volume airflow a circuit low input. I replace the mass airflow sensor, and the crankshaft sensor, just in case. But, none of this worked. Next thing to do is to text the starter, starter solenoid, and see if there are any fuses our relay switches that have been tripped. Does anyone know if it has a relay, or fuse that controls the starting system? Or does that have nothing to do with the mass airflow sensor?
